Screening test: Python and ML questions medium level. Needs medium level fast coding skills. Round 1 : Taken by Lead DS from outside India who is a very cool person. Came prepared for DS case round. Asked ML and Data questions. Listened very patiently Round 2: Some India Analytics Head. Came 10 min late to the Interview and ended up in 30 min, while this was scheduled for 1 hour. The person was not prepared with anything. Didn't have time to listen. Didn't ask a single proper question. Asked 2-3 discrete topics and used to end them abruptly. God knows what he was looking for.

The interview consisted of a total of five rounds, and I'm currently at round 4. It started with a code signal online assessment (tested basic knowledge about data cleaning, data filtering, data joining with pandas as well as some simple ML with scikit). Then the first three rounds are technical case interviews. Each round consisted of about 10-15 mins for introductions, and 30-35 mins for a technical case interview, and then about 5 - 10 mins for questions.
